Well, then.

Just got home from the hospital. Ankle is sprained. The snap-snap I heard was likely the ligaments across the top of my foot letting go.

So ... Ibuprofen every eight hours, wearing two or three sports socks on that foot, ice four times a day, and, oh yeah, it could take three months for the swelling to go away.

If it were broken, I'd at least have a cast and a nice obvious reason for limping everywhere. Now I just look like a zombie from Scooby Doo.

Oh well. At least now I know. *grin*
